As of Oct. 15, Dereon Jayronne Kelly, 22, also known as Dereon Tayronne Kelley, was enrolled at OLLU and lived in The Providence Dorm, the affidavit says. A university spokesman confirmed he is a current student who transferred there in late August.

Kelly is accused of using a computer on the dorm's third floor to send three emails Oct. 18 and 19 to a Texas State employee who works from her home in Harris County.

“I will blow texas state up to small pieces starting with the admissions office today at three central time,” said the initial threat, sent at 7:20 a.m., according to the document.

Over the next 17 hours, the employee received two more threatening emails, the last of which said, “I will not be arrested because they have no proof I did anything because I never brought the bomb on campus but I will tomorrow and they will not be able to find me because im at my house I hate texas state for life the police better not come back here to my house either my family will not tell them where I am at or whose desktop im on.”

Kelly is also suspected in a bomb threat emailed to Texas A&M University in College Station the next day, officials said. It was sent via the same email account used in the Texas State threats but in this instance reportedly from Kelly's cellphone.

He was arrested on outstanding warrants Oct. 19 and charged with making a terroristic threat 10 days later. The Associated Press reported Kelly was also charged on Nov. 2 with violating the Federal Explosive Materials Statute for using the Internet “to convey a false threat involving an explosive device in order to intimidate individuals at Texas State University.”

According to Brazos County records, Kelly remains jailed there on three Dallas County warrants, a Bryan Police Department warrant for assault by contact, and the terroristic threat charge. His bail totals $152,500.

Kelly allegedly used his girlfriend's email account to send the threats while the couple were in a fight, the affidavit says. Brittany Henderson, 19, was arrested in connection with the Texas State threat on Oct. 31 and remains jailed in Hays County under three counts of making a terroristic threat and three counts of making a false alarm; bail totals $40,500.

AP reported that Henderson was once but is no longer a person of interest in the A&M case, and that she's retained a Bryan attorney and will be “asserting her innocence” of any involvement.

The affidavit says that while allegedly emailing the threats to the universities, Kelly was feverishly sending text messages to Henderson. The first was sent at 7:08 a.m., 13 minutes before the Texas State employee received the first threatening email.

“You know what I am trippin hard baby I got pissd off now I gotta deal with it whenever you ready to talk to me I am sorry baby I love you,” said Kelly's first text message to Henderson.

Ten minutes after Bryan police made contact with Henderson in response to the Texas State investigation, Kelly sent a third text: “I hav beat myself up all morning for last nite please talk to me.” About eight hours later, he wrote, “And I logged into your email.”

Minutes before he allegedly sent the second Texas State threat, Kelly texted his girlfriend, “Answer the phone I need to tell you something you gone hate me for it but hey.”

Interviewed the day he was arrested, and hours after he allegedly sent an email to A&M's help desk that said, “Campus will be bombed at twelve this afternoon,” Kelly admitted to using Henderson's email account. Later, he said the phone number traced to the A&M threat was for a cellphone for which he pays $50 a month, the affidavit says.

The incidents at both schools required responses from a barrage of law enforcement, although the cost of the evacuations has not yet been tallied. In San Marcos, the Undergraduate Admissions Building and two residence halls were evacuated; the A&M threat, which was more general, prompted the evacuation of the entire 800-building, 5,500-acre campus, AP reported.
